i have an 06 600 f4i and i purchased a replacement factory exhaust for mine since i wrecked.it came from an 04' model. i noticed that it doesnt have the O2 port in it or the catallic converter. will this be ok to run?i guess maybe i just need to weld in a boss for the sensor.........

 

tap and weld a nut for the sensor...or go O2 sensor eliminator.
you got a non-cali model, hence no sensor hole.

 

pay 15.00 and get the o2 elemation kit from powercommander.com
